FIELD OF THE INVENTION

The present invention provides novel substituted N-phenyl-5-phenyl-pyrazolin-2-yl amides and derivatives thereof as cannabinoid receptor antagonists/inverse agonists and pharmaceutical compositions thereof and methods of using the same for treating obesity, diabetes, dyslipidemias, cardiovascular disorders, and/or hepatic disorders. More particularly, the present invention relates to a novel method for treating obesity, diabetes, dyslipidemias, cardiovascular disorders and/or hepatic disorders using a novel substituted N-phenyl-5-phenyl-pyrazolin-2-yl amides and derivatives thereof.

BACKGROUND OF THE INVENTION

Obesity is associated with an increase in the overall amount of adipose tissue (i.e., body fat), especially adipose tissue localized in the abdominal area. Obesity has reached epidemic proportions in the United States. The prevalence of obesity has steadily increased over the years among all racial and ethnic groups. The most recent data from the Centers for Disease Control and Prevention, and the National Center for Health Statistics report 66% of the adult population overweight (BMI, 25.0-29.9), 31% obese (BMI, 30-39.9), and 5% extremely obese (BMI, ≧40.0). Among children aged 6 through 19 years, 32% were overweight and 17% were obese. This translates to 124 million Americans medically overweight, and 44 million of these deemed obese. Obesity is responsible for more than 300,000 deaths annually, and will soon overtake tobacco usage as the primary cause of preventable death in the United States. Obesity is a chronic disease that contributes directly to numerous dangerous co-morbidities, including type 2 diabetes, cardiometabolic diseases, hepatic disorders, cardiovascular disease, inflammatory diseases, premature aging, and some forms of cancer. Type 2 diabetes, a serious and life-threatening disorder with growing prevalence in both adult and childhood populations, is currently the 7^(th) leading cause of death in the United States. Since more than 80% of patients with type 2 diabetes are overweight, obesity is the greatest risk factor for developing type 2 diabetes. Increasing clinical evidence indicates that the best way to control type 2 diabetes is to reduce weight.

The most popular over-the counter drugs for the treatment of obesity, phenylpropanolamine and ephedrine, and the most popular prescription drug, fenfluramine, were removed from the marketplace as a result of safety concerns. Drugs currently approved for the long-term treatment of obesity fall into two categories: (a) CNS appetite suppressants such as sibutramine and rimonabant, and (b) gut lipase inhibitors such as orlistat. CNS appetite suppressants reduce eating behavior through activation of the ‘satiety center’ in the brain and/or by inhibition of the ‘hunger center’ in the brain. Gut lipase inhibitors reduce the absorption of dietary fat from the gastrointestinal (GI) tract. Although appetite suppressants and gut lipase inhibitors work through very different mechanisms, they share in common the same overall goal of reducing body weight secondary to reducing the amount of calories that reach the systemic circulation. Unfortunately, these indirect therapies produce only a modest initial weight loss (approximately 5% compared to placebo) that is usually not maintained. After one or two years of treatment, most patients return to or exceed their starting weight. In addition, most approved anti-obesity therapeutics produce undesirable and often dangerous side effects that can complicate treatment and interfere with a patient's quality of life.

The lack of therapeutic effectiveness, coupled with the spiraling obesity epidemic, positions the ‘treatment of obesity’ as one of the largest and most urgent unmet medical needs. There is, therefore, a real and continuing need for the development of improved medications that treat or prevent obesity.

The endocanabinoid system, comprised of the canabinoid receptors (CB1 and CB2) and their endogenous ligands (e.g., anandamide, 2-AG), plays a prominent role in the control of food intake and energy metabolism. CB1 receptors are widely expressed in the brain, including cortex, hippocampus, amygdala, pituitary and hypothalamus. CB1 receptors have also been identified in numerous peripheral organs and tissues, including thyroid gland, adrenal gland, reproductive organs, adipose tissue, liver, muscle, pancreas, and gastrointestinal tract. CB2 receptors are localized almost exclusively in immune and blood cells [Endocrine Reviews 2006, 27, 73].

The plant-derived cannabinoid agonist Δ⁹-tetrahydrocannabinol (Δ⁹-THC), the main psychoactive component of marijuana, binds to both CB1 and CB2 receptors. Δ⁹-THC is widely reported to increase appetite and food intake (hyperphagia) in humans and in animals. This hyperphagic effect is largely blocked by pretreatment with selective CB1 receptor blockers (i.e., CB1 blockers) (e.g., rimonabant (SR141716A, Acomplia®)), strongly supporting the belief that CB1 receptor activation mediates the hyperphagic effect of Δ⁹-THC, [Endocrine Reviews 2006, 27, 73].

In humans, rimonabant produces a clinically meaningful weight loss in obese patients. Obese patients also experience improvements in diabetic and cardiometabolic risk factors associated with obesity, including an increase in the level of high density lipoprotein cholesterol (HDL), and decreases in triglycerides, glucose, and hemoglobin A1c (HbA1c, a marker of cumulative exposure to glucose) levels. Rimonabant also produces greater reductions in abdominal fat deposits, which are a known risk factor for diabetes and heart disease [Science 2006, 311, 323]. Taken together, these improvements in adiposity and cardiometabolic risk factors produce an overall decrease in the prevalence of the metabolic syndrome [Lancet 2005, 365, 1389 and NEJM 2005, 353, 2121].

In patients with type 2 diabetes not currently treated with other anti-diabetic medications, rimonabant was shown to significantly improve blood sugar control and weight, as well as other risk factors such as HDL and triglycerides, when compared to placebo (International Diabetes Federation World Diabetes Congress, Cape Town, South Africa, 2006). After six months of treatment, HbA1c levels were significantly lowered by 0.8% from a baseline value of 7.9 as compared to a reduction of 0.3% in the placebo group. These results are consistent with preclinical studies that demonstrate improved glycemic and lipid control in diabetic and dyslipedemic mice, rats, and dogs (Pharmacology Biochemistry & Behavior, 2006, 84, 353; American Journal of Physiology, 2003, 284, R345; American Diabetes Association Annual Meeting, 2007; Abstract Number 0372-OR).

The beneficial effects of rimonabant on diabetic and cardiometabolic risk factors such as high blood pressure, insulin resistance, and elevated triglycerides cannot be explained by diet-related weight loss alone. For example, in patients receiving 20 mg of rimonabant, only approximately 50% of the beneficial effects on triglycerides, fasting insulin, and insulin resistance can be accounted for by weight loss secondary to reduced food intake. These results suggest a direct pharmacological effect of CB1 antagonists on glucose and lipid metabolism, in addition to indirect effects on metabolism secondary to hypophagia-mediated weight loss [Science 2006, 311, 323 and JAMA 2006, 311, 323]. Taken together, these results suggest that CB1 antagonists might be effective in the treatment of diabetes, dyslipidemias, cardiovascular disorders (e.g., atherosclerosis, hypertension), and hepatic disorders (e.g., cirrhosis, fatty liver diseases), even in patients that are not clinically overweight or obese.

The CB1 receptor is one of the most abundant and widely distributed G protein-coupled receptors in the mammalian brain. It is believed that the appetite-suppressant properties of CB1 antagonists are mediated through an interaction with CB1 receptors in the hypothalamus (regulation of food intake), and in the mesolimbic region (rewarding properties of food). However, CB1 receptors are far more broadly distributed in brain (e.g., neocortex, hippocampus, thalamus, cerebellum, and pituitary), and while interacting with targeted CB1 receptors in hypothalamus and mesolimbic regions to suppress appetite, CB1 antagonists have equal access to non-targeted CB1 receptors that have little if any role in appetite control. Binding to non-targeted receptors can often lead to unwanted side effects of CNS drugs [Endocrine Reviews 2006, 27: 73]. The CB1 blockers rimonabant and taranabant produce psychiatric and neurological side effects. These include depressed mood, anxiety, irritability, insomnia, dizziness, headache, seizures, and suicidality.

These side effects are dose-related and appear pronounced at the most efficacious weight-reducing doses of rimonabant and taranabant (JAMA 2006, 311, 323; Cell Metabolism 2008, 7, 68). The occurrence of therapeutic efficacy (appetite suppression) and side effects over the same dose range strongly suggest that both effects are mediated through concurrent antagonism of CB1 receptors in both ‘targeted’ and ‘non-targeted’ brain regions. Brain-penetrant CB1 blockers do not selectively target CB1 receptors in efficacy brain regions, while ignoring CB1 receptors in side effect brain regions.

The beneficial effects of the CB1 antagonist rimonabant on body weight, adiposity, and diabetic and cardiometabolic risk factors such as high blood pressure, insulin resistance and blood lipids cannot be explained by weight loss derived from CNS-mediated appetite suppression alone [JAMA 2006, 311, 323]. Approximately 50% of the benefit is likely derived from an interaction with CB1 receptors in peripheral tissues known to play an active role in metabolism. These include adipose tissue, liver, muscle, pancreas, and gastrointestinal tract.

Rosonabant and other brain penetrating compounds are described in US 2007/0073056. These compounds have the following formula:

wherein R¹ and R² can be aryl groups and C(═X)R³ can be an amide or thioamide group. The compounds of US 2007/0073056 are not considered to be part of the present invention.

In view of the above, it is highly desirable to find effective and highly selective CB1 receptor blockers with limited or no CNS adverse side effects, including mood disorders. Particularly, it is desirable to find compounds that preferentially target CB1 receptors in peripheral tissues (e.g., adipose tissue, liver, muscle, pancreas, and gastrointestinal tract), while sparing CB1 receptors in brain. In this way, peripherally-mediated beneficial effects of CB1 blockers should be maintained, whereas CNS side effects should be reduced or eliminated. This should provide a novel opportunity to develop safer alternatives to highly brain penetrant CB1 blockers for the prevention or treatment of obesity, diabetes, dyslipidemias, cardiovascular disorders, and/or hepatic disorders.

DETAILED DESCRIPTION OF THE INVENTION

All references cited herein are hereby incorporated in their entirety herein by reference.

A CB1 blocker is a neutral CB1 receptor antagonist and/or a CB1 receptor inverse agonist.

The present invention is based on the finding that a CB1 receptor blocker has beneficial effects on metabolic disorders including obesity, diabetes, dyslipidemias, and cardiovascular and hepatic diseases that cannot be explained by weight loss derived from CNS-mediated appetite suppression alone, and that this effect is mediated, at least in part, through interaction at peripheral CB1 receptors. To this end, the present invention provides compounds that are designed to preferentially target CB1 receptors in peripheral tissues (e.g., adipose tissue, liver, muscle, pancreas, and gastrointestinal tract), while sparing CB1 receptors in brain. With these types of compounds, peripherally-mediated beneficial effects of CB1 blockers should be maintained, whereas CNS side effects should be reduced or eliminated.

The compounds of the present invention have been designed to have reduced CNS exposure by virtue of their inability or limited ability to penetrate the blood-brain barrier (BBB), or by their participation in active transport systems, thus reducing centrally mediated side-effects, a potential problem with many anti-obesity agents. It is expected that the peripherally restricted compounds of the present invention will have no or very limited CNS effects, including mood disorders, seizures, and suicidality. Thus, their peripherally mediated CB1 blocking properties should provide therapeutic agents with greater safety.

Moreover, if the maximum dosage of a drug used in the treatment of obesity, diabetes, dyslipidemias, cardiovascular disorders, and/or hepatic disorders is limited as a result of CNS side effects (e.g., seizures, depression, anxiety, suicidality, movement disorders, and hyperactivity), incorporation of a peripherally restricting group in such a drug would lower the brain concentration of the drug relative to the concentration in the systemic circulation, thereby affording the opportunity to increase the dosage employed to treat the peripheral disorder (e.g., obesity, diabetes, dyslipidemias, cardiovascular disorders, and/or hepatic disorders). The increased dosage may provide greater therapeutic efficacy, as well as a more rapid onset of therapeutic action.

“Pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include, but are not limited to, those derived from inorganic and organic acids selected from 1,2-ethanedisulfonic, 2-acetoxybenzoic, 2-hydroxyethanesulfonic, acetic, ascorbic, benzenesulfonic, benzoic, bicarbonic, carbonic, citric, edetic, ethane disulfonic, ethane sulfonic, fumaric, glucoheptonic, gluconic, glutamic, glycolic, glycollyarsanilic, hexylresorcinic, hydrabamic, hydrobromic, hydrochloric, hydroiodide, hydroxymaleic, hydroxynaphthoic, isethionic, lactic, lactobionic, lauryl sulfonic, maleic, malic, mandelic, methanesulfonic, napsylic, nitric, oxalic, pamoic, pantothenic, phenylacetic, phosphoric, polygalacturonic, propionic, salicyclic, stearic, subacetic, succinic, sulfamic, sulfanilic, sulfuric, tannic, tartaric, and toluenesulfonic.

The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound that contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, non-aqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are useful. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 18th ed., Mack Publishing Company, Easton, Pa., 1990, p 1445, the disclosure of which is hereby incorporated by reference.

“Therapeutically effective amount” includes an amount of a compound of the present invention that is effective when administered alone or in combination to treat obesity, diabetes, dyslipidemias, cardiovascular disorders, hepatic disorders, and a combination or comorbitity thereof, or another indication listed herein. “Therapeutically effective amount” also includes an amount of the combination of compounds claimed that is effective to treat the desired indication. The combination of compounds can be a synergistic combination. Synergy, as described, for example, by Chou and Talalay, Adv. Enzyme Regul. 1984, 22:27-55, occurs when the effect of the compounds when administered in combination is greater than the additive effect of the compounds when administered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at sub-optimal concentrations of the compounds. Synergy can be in terms of lower cytotoxicity, increased effect, or some other beneficial effect of the combination compared with the individual components.

Obesity is defined as having a body mass index (BMI) of 30 or above. The index is a measure of an individual's body weight relative to height. BMI is calculated by dividing body weight (in kilograms) by height (in meters) squared. Normal and healthy body weight is defined as having a BMI between 20 and 24.9. Overweight is defined as having a BMI≧25. Obesity has reached epidemic proportions in the U.S., with 44 million obese Americans, and an additional eighty million deemed medically overweight.

Obesity is a disease characterized as a condition resulting from the excess accumulation of adipose tissue, especially adipose tissue localized in the abdominal area. It is desirable to treat overweight or obese patients by reducing their amount of adipose tissue, and thereby reducing their overall body weight to within the normal range for their sex and height. In this way, their risk for co-morbidities such as diabetes, dyllipidemias, and cardiovascular and hepatic diseases will be reduced. It is also desirable to prevent normal weight individuals from accumulating additional, excess adipose tissue, effectively maintaining their body weights at a BMI<25, and preventing the development of co-morbidities. It is also desirable to control obesity, effectively preventing overweight and obese individuals from accumulating additional, excess adipose tissue, reducing the risk of further exacerbating their co-morbidities.

Type 2 Diabetes or Diabetes mellitus type 2 or (formerly called non-insulin-dependent diabetes mellitus (NIDDM), or adult-onset diabetes) is a metabolic disorder that is primarily characterized by insulin resistance, relative insulin deficiency, and hyperglycemia. The World Health Organization definition of diabetes is for a single raised glucose reading with symptoms otherwise raised values on two occasions, of either fasting plasma glucose≧7.0 mmol/l (126 mg/dl) or with a Glucose tolerance test: two hours after the oral dose a plasma glucose≧11.1 mmol/l (200 mg/dl). Type 2 Diabetes is rapidly increasing in the developed world and there is some evidence that this pattern will be followed in much of the rest of the world in coming years. CDC has characterized the increase as an epidemic (Diabetes, Atlanta: Centres for Disease Control, Atlanta, Report no. 2007-05-24). In addition, whereas this disease used to be seen primarily in adults over age 40 (in contrast to Diabetes mellitus type 1), it is now increasingly seen in children and adolescents, an increase thought to be linked to rising rates of obesity in this age group.

Insulin resistance means that body cells do not respond appropriately when insulin is present. Unlike insulin-dependent diabetes mellitus (Type 1), the insulin resistance is generally “post-receptor”, meaning it is a problem with the cells that respond to insulin rather than a problem with insulin production. Type 2 diabetes is presently of unknown etiology (i.e., origin). About 90-95% of all North American cases of diabetes are type 2, and about 20% of the population over the age of 65 has diabetes mellitus Type 2 (Nature, 2001, 414, 6865). Diabetes affects over 150 million people worldwide and this number is expected to double by 2025. About 55 percent of type 2 diabetics are obese-chronic obesity leads to increased insulin resistance that can develop into diabetes (Morbidity and Mortality Weekly Report 2008, 53, 1066). Type 2 diabetes is often associated with obesity, hypertension, elevated cholesterol (combined hyperlipidemia), and with the condition often termed Metabolic syndrome (it is also known as Syndrome X, Reavan's syndrome, or CHAOS). There are several drugs available for Type 2 diabetics, including metformin, thiazolidinediones, which increase tissue insulin sensitivity, α-glucosidase inhibitors which interfere with absorption of some glucose containing nutrients, and peptide analogs that must be injected.

Dyslipidemia is the presence of abnormal levels of lipids and/or lipoproteins in the blood. Lipids (fatty molecules) are transported in a protein capsule, and the density of the lipids and type of protein determines the fate of the particle and its influence on metabolism. Lipid and lipoprotein abnormalities are extremely common in the general population, and are regarded as a highly modifiable risk factor for cardiovascular disease due to the influence of cholesterol, one of the most clinically relevant lipid substances, on atherosclerosis. In addition, some forms may predispose to acute pancreatitis.

In western societies, most dyslipidemias are hyperlipidemias; that is, an elevation of lipids in the blood, often due to diet and lifestyle. The prolonged elevation of insulin levels can also lead to dyslipidemia. The most prevalent hyperlipidemias include: hypercholesterolemia, characterized by elevated cholesterol (usually LDL), hypertriglyceridemia, characterized by elevated triglycerides (TGs); hyperlipoproteinemia, characterized by elevated lipoproteins; hyperchylomicronemia, characterized by elevated chylomicrons; and combined hyperlipidemia, characterized by elevated LDL and triglycerides. Abnormal decreases in the levels of lipids and/or lipoproteins in the blood also can occur. These include hypocholesterolemia, characterized by lowered cholesterol (usually high density lipoprotein, or HDL); and abetalipoproteinemia, characterized by lowered beta lipoproteins.

Dyslipidemia contributes to the development of atherosclerosis. Causes may be primary (genetic) or secondary. Diagnosis is by measuring plasma levels of total cholesterol, TGs, and individual lipoproteins. Treatment is dietary changes, exercise, and lipid-lowering drugs. A linear relation probably exists between lipid levels and cardiovascular risk, so many people with “normal” cholesterol levels benefit from achieving still lower levels. Normal and abnormal lipid levels have been defined in the Third Report of the Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults. National Institutes of Health, National Heart, Lung, and Blood Institute, 2001.

The treatment of choice for dyslipidemias is lifestyle change, including diet and exercise. Drugs are the next step when lifestyle changes are not effective. Lipid lowering drugs include statins, nicotinic acid, bile acid sequestrants, fibrates, cholesterol absorption inhibitors, and combination treatments (e.g., niacin and a statin). These agents are not without adverse effects, including flushing and impaired glucose tolerance (nicotinic acid), bloating, nausea, cramping, and constipation (bile acid sequestrants). Bile acid sequestrants may also increase TGs, so their use is contraindicated in patients with hypertriglyceridemia. Fibrates potentiate muscle toxicity when used with statins, and may increase LDL in patients with high TGs.

There are many kinds of hepatic (i.e., liver) diseases. Viruses cause some of them, like hepatitis A, hepatitis B and hepatitis C. Others can be the result of drugs, poisons or drinking too much alcohol. If the liver forms scar tissue because of an illness, it's called cirrhosis. Jaundice, or yellowing of the skin, can be one sign of hepatic disease. Cancer can affect the liver. Hepatic diseases such as hemochromatosis can be inherited. Additional liver diseases include nonalcohol steatohepatitis (NASH), alcoholic liver disease, cholangiocarcinoma, hepatic encephalopathy, hepatic failure, liver abscess, liver tumors, liver coagulopathy, glycogen storage diseases, portal hypertension, primary biliary cirrhosis, and primary sclerosing cholangitis.

There are few good treatment options for liver diseases. Options include lifestyle change (including diet and exercise), liver transplantation, and insertion of a transjugular intrahepatic portosystemic shunt that is placed in veins in the middle of the liver to improve blood flow to and from the organ. There are few effective drug treatment options for hepatic diseases. Interferon is an FDA-approved drug for the treatment of viral hepatitis. The chimeric protein Hyper-IL-6 dramatically enhances hepatocyte proliferation and is currently being evaluated as a pharmacological treatment for liver injury.

Drugs enter the CNS from the systemic circulation by crossing the blood-brain barrier (BBB). The BBB is a highly specialized ‘gate-keeper’ that protects the brain by preventing the entry of many potentially harmful substances into the CNS from the systemic circulation. Much is known about the BBB, and of the physical-chemical properties required for compounds transported across it.

Drugs that do not cross the BBB into the CNS or that are readily eliminated through transport mechanisms (J. Clin. Invest. 1996, 97, 2517) are known in the literature and have low CNS activity due to their inability to develop brain levels necessary for pharmacological action. The BBB has at least one mechanism to remove drugs prior to their accumulation in the CNS. P-Glycoproteins (P-gp) localized in plasma membrane of the BBB can influence the brain penetration and pharmacological activity of many drugs through translocation across membranes. The lack of accumulation into the brain by some drugs can be explained by their active removal from the brain by P-gp residing in the BBB. For example, the typical opioid drug loperamide, clinically used as an antidiarrheal, is actively removed from the brain by P-gp, thus explaining its lack of opiate-like CNS effects. Another example is domperidone, a dopamine receptor blocker that participates in the P-gp transport (J. Clin. Invest. 1996, 97, 2517). Whereas dopamine receptor blockers that cross the BBB can be used to treat schizophrenia, the readily-eliminated domperidone can be used to prevent emesis, without the likelihood of producing adverse CNS effects.

In addition to the above compounds, agents possessing structural characteristics that retard or prevent BBB penetration or contribute to participation in active elimination processes have been identified in various classes of therapeutics. These include antihistamines (Drug Metab. Dispos. 2003, 31, 312), beta-adrenergic receptor antagonists (Eur. J. Clin. Pharmacol. 1985, 28, Suppl: 21; Br. J. Clin. Pharmacol., 1981, 11, 549), non-nucleoside reverse transcriptase inhibitors (NNRTIs, J. Pharm. Sci., 1999, 88, 950), and opioid antagonists. This latter group has been tested in relation to their activity in the gastrointestinal tract. These peripherally selective opioid antagonists are described in various US patents as being useful in the treatment of non-CNS pathologies in mammals, in particular those of the gastrointestinal tract [see U.S. Pat. No. 5,260,542; U.S. Pat. No. 5,434,171; U.S. Pat. No. 5,159,081; and U.S. Pat. No. 5,270,238].

Other types of non-brain penetrant compounds can be prepared through the creation of a charge within the molecule. Thus, the addition of a methyl group to the tertiary amine functionality of the drugs scopolamine or atropine, unlike the parent molecules, prevents their passage across the BBB through the presence of a positive charge. However, the new molecules (methyl-scopolamine and methyl-atropine) retain their full anticholinergic pharmacological properties. As such, these drugs can also be used to treat peripheral diseases, without the concern of adverse CNS effects. The quaternary ammonium compound methylnaltrexone is also used for the prevention and/or treatment of opioid-induced gastrointestinal side effects associated with opioid administration (J. Pharmacol. Exp. Ther. 2002, 300, 118).

The discovery that the anti-obesity activity of cannabinoid receptor blockers may in part be mediated by a non-CNS mechanism could make it beneficial for the compounds of the present invention to be peripherally restricted (i.e., have an inability or limited ability to cross the BBB, or be readily eliminated from the brain through active transport systems). It may be desirable for the compounds of the present invention to be peripherally restricted, which in turn will result in no or very limited CNS effects. Compounds that provide peripherally mediated efficacy in treating obesity, diabetes, dyslipidemias, cardiovascular disorders, hepatic disorders, a comorbitity thereof, or a combination or should result in therapeutic agents with greater safety. It can be desirable that the compounds of the present invention, when administered in a therapeutically effective amount, have no or very limited CNS effects. It can also be desirable that the lack of CNS effects is a result of the compounds of the present invention having minimal brain concentrations when administered in therapeutically effective amounts. In this context, minimal brain concentrations means levels that are too low to be therapeutically effective for the treatment of a CNS indication or too low to cause significant or measurable deleterious or undesired side effects, or both.

Rosonabant (Compound IIa when X═H; Y, X′, and Y′═Cl; V═H; Z═H; Q=N; L=CO, and n=2) is a drug that crosses the BBB and is indicated for the treatment of obesity. In compound AA, one of R, R¹, R², X, X¹, V and Z is a group capable of reducing or limiting the CNS activity of compound AA. This reduced or limited CNS activity occurs via at least one of R, R¹, R², X, X¹, V and Z being a group that either limits compound AA's ability to cross the BBB relative to that of rosonabant or enables it to be actively removed from the brain at a rate greater than that of rosonabant. Examples of the amount of compound AA present in the brain can include (a) from 50, 55, 60, 65, 70, 75, 80, 85, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, to 100% lower than rosonabant, (b) from 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, to 100% lower than rimonabant, and (c) from 98, 99, to 100% lower than rimonabant, when administered at the same dosage.

The compounds of the present invention are expected to be cannabinoid receptor antagonists or inverse agonists (e.g., have activity at ≦10 μM). Representative compounds have been tested and shown to be active (e.g., see Tables A, B, and C).

An inverse agonist is a compound that not only blocks the action of the endogenous agonist at the receptor, but also exhibits its own activity which is usually the opposite of that shown by the agonist. Inverse agonists are also effective against certain types of receptors (e.g. certain histamine receptors/GABA receptors) that have intrinsic activity without the interaction of a ligand upon them (also referred to as ‘constitutive activity’).

Most methods of treating obesity are dependent on a significant reduction in energy intake, either by a decrease in food intake (e.g., sibutramine) or by inhibition of fat absorption (e.g., orlistat). In the present invention, adipose tissue may be reduced in the absence of a significant reduction in food intake. The weight loss, as a result of the present invention, comes from the treatment with a compound of the present invention, largely independent of, though not totally dissociated from, appetite and food intake. It can be desirable that adipose tissue loss occurs while food intake is maintained, increased or (a) about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20% below the normal range of the subject prior to being treated in accordance with the present invention (i.e., its pre-administration level), (b) about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15% below its pre-administration level, (c) about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% below its pre-administration level, or (d) about 1, 2, 3, 4, or 5% below its pre-administration level.

In some cases, loss of adipose tissue can be accompanied by a concomitant loss of lean muscle mass. This is particularly evident in cancer patients who show a generalized wasting of body tissues, including adipose tissue and lean muscle mass. In the present invention, however, it can be desirable for body fat to be significantly reduced in the absence of a significant reduction in lean body mass. Adipose tissue loss comes from treatment with a compound of the present invention, independent of a significant change in lean body mass. Thus, adipose tissue loss can occur while lean body mass is maintained, increased, or (a) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30% below the normal range of the subject prior to being treated in accordance with the present invention (i.e., its pre-administration level), (b) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15% below pre-administration levels, (c) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% below pre-administration levels, or (d) is no more than about 1, 2, 3, 4, or 5% below pre-administration levels.

In some cases, loss of adipose tissue can be accompanied by a concomitant loss of water mass. This is particularly evident with diet regimens that promote dehydration. In the present invention, it can be desirable for body fat to be significantly reduced in the absence of a significant reduction in water mass. In other words, adipose tissue loss comes from treatment with a compound of the present invention, independent of a significant change in water mass. It can be desirable that adipose tissue loss occurs while water mass is maintained, increased, or (a) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30% below the normal range of the subject prior to being treated in accordance with the present invention (i.e., its pre-administration level), (b) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15% below pre-administration levels, (c) is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% below pre-administration levels, or (d) is no more than about 1, 2, 3, 4, or 5% below pre-administration levels.

Sibutramine and orlistat are currently marketed for use in the treatment of obesity, albeit weight loss is achieved through entirely different mechanism of action. Sibutramine inhibits the neuronal reuptake of serotonin and noradrenaline, and orlistat inhibits gut lipase enzymes that are responsible for breaking down ingested fat.

Cannabinoid receptor blockers can promote weight loss through inhibition of peripheral cannabinoid receptors, a mechanism entirely different from appetite suppressants, gut lipase inhibitors, and other agents with similar indications (e.g., serotonin agonists, leptin, fatty acid synthase inhibitors, and monoamine oxidase (MAO) inhibitors). Co-administration of a cannabinoid receptor blocker together with one or more other agents that are useful for treating the indications described above (e.g., obesity, diabetes, dyslipidemias, cardiovascular disorders, hepatic disorders, and a combination thereof) is expected to be beneficial, by producing, for example, either additive or synergistic effects. Examples of additional agents include an appetite suppressant, a lipase inhibitor, and a MAO inhibitor (e.g., MAO-B and a combination of MAO-A/B). Therefore, the present invention provides a method of treating obesity, diabetes, dyslipidemias, cardiovascular disorders, and/or hepatic disorders, and a combination thereof, comprising administering a therapeutically effective amount of a compound of the present invention and a second component effective for treating the desired indication.

Examples of second components useful for treating diabetes include (a) insulin sensitizers including (i) PPAR-γ agonists such as the glitazones (e.g. troglitazone, pioglitazone, englitazone, MCC-555, rosiglitazone), and compounds disclosed in WO97/27857, 97/28115, 97/28137, and 97/27847; and (ii) biguanides such as metformin and phenformin; (b) insulin or insulin mimetics; (c) sulfonylureas such as tolbutamide and glipizide, or related materials; (d) α-glucosidase inhibitors (e.g., acarbose); (e) cholesterol lowering agents such as (i) HMG-CoA reductase inhibitors (lovastatin, simvastatin, pravastatin, fluvastatin, atorvastatin, rivastatin, and other statins), (ii) sequestrants (e.g., cholestyramine, colestipol, and dialkylaminoalkyl derivatives of a cross-linked dextran), (iii) nicotinyl alcohol, nicotinic acid or a salt thereof, (iv) PPAR-α agonists (e.g., fenofibric acid derivatives including gemfibrozil, clofibrate, fenofibrate, and bezafibrate), (v) inhibitors of cholesterol absorption (e.g., β-sitosterol) and acyl CoA:cholesterol acyltransferase inhibitors (e.g., melinamide), and (vi) probucol; (f) PPAR-α/γ agonists; (g) antiobesity compounds (described previously); (h) ileal bile acid transporter inhibitors; (i) insulin receptor activators, (j) dipeptidyl peptidase IV, or DPP-4 inhibitors (sitagliptin, vildagliptin and other DPP-4 inhibitors (k) exenatide, (l) pramLintide, (m) FBPase inhibitors, (n) glucagon receptor antagonists, (o) glucagon-like peptide-1, and (p) the glucagon-like peptide-1 analogues (liraglutide, and others).

The compounds of the present invention are expected to be CB1 receptor blockers and are expected to be useful for treating diseases mediated by the CB₁ receptor. The compounds of the present are expected to possess an affinity in vitro for the central and/or peripheral cannabinoid receptors under the experimental conditions described by Devane et al., Molecular Pharmacology, 1988, 34, 605-613. The compounds according to the invention are also expected to possess an affinity for the cannabinoid receptors present on preparations of electrically stimulated isolated organs. These tests can be performed on guinea-pig ileum and on mouse vas deferens according to Roselt et al., Acta Physiologica Scandinavia 1975, 94, 142-144, and according to Nicolau et al., Arch. Int. Pharmacodyn, 1978, 236, 131-136.

CB1 receptor affinities can be determined using membrane preparations of Chinese hamster ovary (CHO) cells in which the human cannabinoid CB1 receptor is stably transfected (Biochem J. 1991, 279, 129-134) in conjunction with [3H]CP-55,940 as radioligand. After incubation of a freshly prepared cell membrane preparation with the [3H]-radioligand, with or without addition of test compound, separation of bound and free ligand is performed by filtration over glass fiber filters. Radioactivity on the filter is measured by liquid scintillation counting. The IC₅₀ values can be determined from at least three independent measurements.

Formulations and Dosages

In the present invention, the compound(s) of the present invention can be administered in any convenient manner (e.g., enterally or parenterally). Examples of methods of administration include orally and transdermally. One skilled in this art is aware that the routes of administering the compounds of the present invention may vary significantly. In addition to other oral administrations, sustained release compositions may be favored. Other acceptable routes may include injections (e.g., intravenous, intramuscular, subcutaneous, and intraperitoneal); subdermal implants; and, buccal, sublingual, topical, rectal, vaginal, and intranasal administrations. Bioerodible, non-bioerodible, biodegradable, and non-biodegradable systems of administration may also be used. Examples of oral formulations include tablets, coated tablets, hard and soft gelatin capsules, solutions, emulsions, and suspensions.

If a solid composition in the form of tablets is prepared, the main active ingredient can be mixed with a pharmaceutical vehicle, examples of which include silica, starch, lactose, magnesium stearate, and talc. The tablets can be coated with sucrose or another appropriate substance or they can be treated so as to have a sustained or delayed activity and so as to release a predetermined amount of active ingredient continuously. Gelatin capsules can be obtained by mixing the active ingredient with a diluent and incorporating the resulting mixture into soft or hard gelatin capsules. A syrup or elixir can contain the active ingredient in conjunction with a sweetener, which is typically calorie-free, an antiseptic (e.g., methylparaben and/or propylparaben), a flavoring, and an appropriate color. Water-dispersible powders or granules can contain the active ingredient mixed with dispersants or wetting agents or with suspending agents such as polyvinylpyrrolidone, as well as with sweeteners or taste correctors. Rectal administration can be effected using suppositories, which are prepared with binders melting at the rectal temperature (e.g., cocoa butter and/or polyethylene glycols). Parenteral administration can be effected using aqueous suspensions, isotonic saline solutions, or injectable sterile solutions, which contain pharmacologically compatible dispersants and/or wetting agents (e.g., propylene glycol and/or polyethylene glycol). The active ingredient can also be formulated as microcapsules or microspheres, optionally with one or more carriers or additives. The active ingredient can also be presented in the form of a complex with a cyclodextrin, for example α-, β-, or γ-cyclodextrin, 2-hydroxypropyl-β-cyclodextrin, and/or methyl-β-cyclodextrin.

The dose of the compound of the present invention administered daily will vary on an individual basis and to some extent may be determined by the severity of the disease being treated (e.g., obesity, diabetes, dyslipidemias, cardiovascular disorders, and hepatic disorders). The dose of the compound of the present invention will also vary depending on the compound administered. Examples of dosages of compounds of the present invention include from about 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 76, 80, 85, 90, 95, to 100 mg/kg of mammal body weight. The compound can be administered in a single dose or in a number of smaller doses over a period of time. The length of time during which the compound is administered varies on an individual basis, and can continue until the desired results are achieved (i.e., reduction of body fat, or prevention of a gain in body fat). Therapy could, therefore, last from 1 day to weeks, months, or even years depending upon the subject being treated, the desired results, and how quickly the subject responds to treatment in accordance with the present invention.

The compounds of the present invention can be prepared in numerous ways known to one skilled in the art of organic synthesis through construction of the pyrazoline carboxylic acid with various substituents on the heterocyclic nucleus. Methods for the construction of this variably substituted pyrazoline carboxylic acids are cited in various literature publications and published patent or patent applications (e.g., see EP 1743888, 1743889; Synthetic Communications, 26 2229 (1996); Tetrahedron, 81, 5235 (2005); Tetrahedron Asymmetry, 12, 1923 (2001); U.S. Pat. No. 6,028,084; US Patent Application No. 2007/0073056; and EP2006/006961). The respective descriptions are hereby incorporated by reference and form part of the disclosure. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or by variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention. It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene and Wuts (Protective Groups In Organic Synthesis, Wiley and Sons, 1991).

Scheme 1 shows how an appropriately substituted pyrazoline carboxylic acid, upon conversion to the acid chloride using thionyl chloride and subsequent treatment with ethyl N-aminonipecotate, should afford the hydrazide ester (step a). Hydrolysis of the ester with lithium hydroxide and acidification with dilute hydrochloric acid solution should yield the hydrazide carboxylic acid (step b). Treatment of this acid with thionyl chloride followed by ammonia should afford the carboxamide (step c).

Alternatively, the acid chloride generated from the product of step c can be treated with N-amino-2-pyrrolidine methanol O—CH₂CO₂Et derivative to produce the hydrazide ester (step d). Subsequent hydrolysis of this ester with aqueous base should afford the carboxylic acid (step e), and treatment as above with thionyl chloride and ammonia should produce the carboxamide (step f)

Scheme 2 describes how the conversion of a pyrazoline carboxylic acid to its acid chloride using thionyl chloride or oxalyl chloride in dichloroethane at elevated temperatures followed by treatment with ethyl 4-aminocyclohexane carboxylate in the presence of triethyl amine should afford the amide ester (step a). Hydrolysis of the ester with lithium hydroxide and acidification with dilute hydrochloric acid solution should yield the amide carboxylic acid (step b). When this acid is further treated with Boc anhydride (Boc₂O) in THF in the presence of pyridine, followed by a solution of ammonia in THF at 0° C. to ambient temperature, the carboxamido compound should be produced (step c).

Alternatively, a pyrazoline acid chloride can be treated with 2-amino-cyclopentylmethanol-OCH₂CO₂Et derivative to produce the amide ester (step d). Subsequent hydrolysis of this ester with aqueous base should afford the carboxylic acid (step e). Treatment as previously described should also afford the carboxamide (step f).

Scheme 3 depicts the conversion of a pyrazoline carboxylic acid to its acid chloride using thionyl chloride or oxalyl chloride in dichloroethane at ambient to elevated temperatures followed by treatment with an amine such as alanine ethyl ester (A=methyl, m=0) in the presence of an amine such as triethylamine or N-methylmorpholine to afford the amide ester (step a). Hydrolysis of the ester with lithium hydroxide in aqueous THF solution and acidification with dilute hydrochloric acid solution should yield the amide carboxylic acid (step b). This acid can be further treated with Boc anhydride (Boc₂O) in THF in the presence of pyridine, followed by a solution of ammonia in THF at 0° C. to ambient temperature to yield the carboxamido compound (step c, R═H). Treatment of the acid with isobutylchloroformate (IBCF) in dichloromethane in the presence of N-methylmorpholine (NMM) at 0 to −15° C. followed by hydroxylamine hydrochloride at low temperature to ambient temperature should afford the hydroxamic acid (step c, R═OH). Alternatively, the ester from step a can be directly converted to the amide by treatment with ammonia or other primary amines in THF or MeOH at ambient or elevated temperature (step d). Treatment of the acid with IBCF in dichlomethane in the presence of NMM followed by condensation with an amino ester such as ethyl glycine should also produce the dipeptide adduct (step e). Hydrolysis or amidolysis as described above should give the acid or amide, respectively (step f, Z═OH or NH₂). The carboxylic acid can also be treated, as described above, to produce the hydroxamic acid (step f, Z═NHOH).

Scheme 4 illustrates how the treatment of 4-benzyloxybenzaldehyde with ethyl pyruvate in aqueous ethanol solution in the presence of sodium hydroxide at 0° to room temperature over a several hour period should afford, after acidification with hydrochloric acid solution, the oxobutenoic acid (step a). Treatment of the acid with 2,4-dichlorophenyl hydrazine in glacial acetic acid at elevated temperatures for several hours should produce the pyrazoline carboxylic acid (step b). The acid can be esterified with ethanol in the presence of an acid such as sulfuric acid (step c). Removal of the benzyl group via treatment with TFA (step d) and alkylation of the resulting phenol with bromoacetonitrile in the presence of a base, such as potassium carbonate, in a solvent such as DMF at elevated temperature should produce the ether (step e). Hydrolysis of the ester using lithium hydroxide and aqueous THF as described above and subsequent conversion of the carboxylic acid to the acid chloride using thionyl chloride followed by treatment with N-aminopiperidine should afford the hydazide (step f). The nitrile can be converted to the carboxamide using hydrogen peroxide in DMSO containing potassium carbonate (step g).

Scheme 5 shows how the treatment of 3-nitrobenzaldehyde with ethyl pyruvate in aqueous ethanol solution in the presence of sodium hydroxide at 0° to room temperature over a 2-4 hour period should afford, after acidification with hydrochloric acid solution, the oxobutenoic acid (step a). Treatment of the acid with 2,4-dichlorophenyl hydrazine in glacial acetic acid at elevated temperatures for several hours should produce the pyrazoline carboxylic acid (step b). Subsequent conversion of the carboxylic acid to the acid chloride using thionyl chloride followed by treatment with N-aminopiperidine should afford the hydazide (step c). The nitro compound can be reduced using sodium dithionite in aqueous dioxane containing concentrated ammonium hydroxide solution to give the aniline (step d). Reaction of the aniline with ethyl 4-bromocrotonate in acetone at reflux in the presence of potassium carbonate should afford the ester (step e). Hydrolysis of the ester with lithium hydroxide in aqueous THF solution, and acidification with dilute hydrochloric acid solution should yield the carboxylic acid (step f).

Alternatively, the aniline can be treated with ethyl malonyl chloride in the presence of base to yield the ester (step g). The ester can then be hydrolyzed with lithium hydroxide in aqueous THF solution, and after acidification with dilute hydrochloric acid solution should yield the hydrazide carboxylic acid (step h). In both cases, the carboxylic acid products can also be converted to carboxamides using thionyl chloride and ammonia as described above.

Scheme 6 describes how the conversion of the pyrazoline carboxylic acid of Scheme 5 to its acid chloride using thionyl chloride followed by treatment with N-aminopiperidine should afford the hydazide (step a). The nitro compound can be reduced to the aniline using sodium dithionite in aqueous dioxane containing concentrated ammonium hydroxide solution to give the aniline (step b). Reaction of the aniline with methanesulfonyl chloride in the presence of base should afford the sulfonamide (step c). Alternatively, treatment of the aniline with sodium cyanate in aqueous acetic acid solution at room or slightly elevated temperatures should produce the urea (step d).

Scheme 7 depicts how the condensation of a benzaldehyde with ethyl-t-butyl oxalate in the presence of base, such as lithium hexamethydisilazide in a solvent such as ether or THF at 0° to room temperature, should afford, after acidification with hydrochloric acid solution, the keto-ester (step a). Heating this keto-ester with 4-hydrazinobenzoic acid in a solvent such as toluene or ethylene glycol diethyl ether containing glacial acetic acid at elevated temperatures for several hours should produce the pyrazoline ester (step b). Esterification of the benzoic acid with diazomethane in methanol solution should give the methyl ester (step c) which upon further treatment with trifluoroacetic acid in methylene chloride, should afford the pyrazoline carboxylic acid (step d). Subsequent conversion of the carboxylic acid to the acid chloride using thionyl chloride followed by treatment with N-aminopiperidine should afford the hydazide ester (step e). Hydrolysis of the remaining ester with lithium hydroxide in aqueous THF solution, and acidification with dilute hydrochloric acid solution should yield the hydrazide carboxylic acid (step f). The carboxylic acid can then be treated with thionyl chloride followed by ammonia to produce the carboxamido compound (step g).

Scheme 8 illustrates an alternate method of converting a pyrazoline carboxylic acid to a di-amino acid adduct. Reacting a carbobenzyloxy (CBZ) protected amino acid such as alanine with an amino acid ester such as 4-amino-2-hydroxybutyric acid methyl ester in methylene chloride in the presence isobutylchloroformate and N-methylmorpholine (NMM) at −15° C. to room temperature should give the diamino acid adduct. The CBZ-group can then be removed through hydrogenolysis over Pd/C in methanol. Treatment of this amino ester with a pyrazoline carboxylic acid chloride in dichloromethane in the presence of NMM at zero° C. to room temperature should afford the di-amino ester adduct (step a). Hydrolysis of the ester with lithium hydroxide in aqueous THF solution, and acidification with dilute hydrochloric acid solution should yield the hydroxy carboxylic acid (step b). Alternatively, the ester can be treated with ammonia in methanol to yield the carboxamide (step c).

Scheme 9 shows how the treatment of a oxobutenoic acid, prepared as described in Scheme 4, with 4-methoxyphenylhydrazine in a solvent such as glacial acetic acid at elevated temperatures for several hours should produce the pyrazoline carboxylic acid (step a). The acid can be converted to the acid chloride using thionyl chloride followed by treatment with N-aminopiperidine to afford the hydrazide (step b). Demethylation of the ether can be achieved using BBr₃ or TMAH/Al₂Cl₇ (see European Journal Org Chem, 1681(2003)) in methylene chloride at reflux. (step c). Alkylation of the phenol using ethyl bromoacetate in acetone in the presence of potassium carbonate at room temperature to reflux should afford the ester (step d). Hydrolysis of the ester with lithium hydroxide in aqueous THF solution, and acidification with dilute hydrochloric acid solution should yield the carboxylic acid (step e). The carboxylic acid can then be treated with isobutylchloroformate followed by ammonia to produce the aryloxyacetamide (step f).

Scheme 10 describes how the treatment of a oxobutenoic acid when treated with 5-cyanophenylhydrazine, prepared as described in Scheme 4, with 4-methoxyphenylhydrazine in a solvent such as glacial acetic acid at elevated temperatures for several hours should produce the pyrazoline carboxylic acid (step a). Conversion of the carboxylic acid to the acid chloride using thionyl chloride followed by treatment with N-aminopiperidine should afford the hydazide ester (step b). Heating a mixture of the arylnitrile with sodium azide and zinc chloride or zinc bromide in water with vigorous stirring should produce the aryl-tetrazole after acidification with dilute hydrochloric acid solution (step c). Alternatively, the nitrile can be treated with HCl gas in a solution of chloroform and methanol at about −15 to 0° C. to form the imidate ester that can immediately be converted to the carboxamidine by subsequent treatment with ammonium carbonate in methanol (step d).

Scheme 11 depicts how the reaction of 4-chlorobenzaldehyde with 2-ketobutyric acid in methanol in the presence of potassium hydroxide at room temperature to about 45° C. should afford, after acidificatioin with HCl solution, the unsaturated acid (step a). Heating this keto-acid with an aryl hydrazine in a solvent such as glacial acetic acid under a nitrogen atmosphere for 2-4 hours should produce the pyrazoline carboxylic acid (step b) as a mixture of diastereomers. The pyrazoline carboxylic acid can be treated with thionyl chloride in toluene in the presence of a few drops of DMF catalyst at elevated temperatures to produce the acid chloride, which upon treatment with ethyl 1-aminonipecotate or ethyl 1-amino-isonipecotate in the presence of diisopropylethylamine at 0° C. to room temperature should afford the hydrazide esters (step c). Hydrolysis of the ester with lithium hydroxide in aqueous THF solution and acidification with dilute hydrochloric acid solution should yield the hydrazide carboxylic acid (step d). The carboxylic acid can then be treated with thionyl chloride followed by ammonia, or with Boc anhydride in THF in the presence of pyridine, followed by a solution of ammonia in THF at 0° C. to ambient temperature to produce the carboxamido hydrazide (step e).
